Goons often have long limbs to accentuate the lankiness.
And by lil wayne in "A mille" when he says, "I go by them goon rules: if you can't beat'm then you drop'm". FYI Plies, lil wayne, bird man, and gucci man are all Bloods (see lil wayne's verse in shory lo's "they know" remix when he says, "Su-Wu gang, and if you aint wit it then you in the food chain.." (su-wu is a term for blood gang members).
Goons have neckbeards, no real-life social skills, a tendency for whining about dumb superficial crap, and a knack for shutting down anyone who has anything worth making fun of. They're known for their sarcastic and elitist tendencies, though many on the internet find them hilarious.
Usually proud members of such Forums as GBS, BYOB, FYAD, or ADTRW, goons patrol the Awful Forums attempting to type funny jokes while their fingers slip off the keyboard due to Cheetos grease.
Goons spew overused catchphrases like "Do you have stairs in your house?" or "All your base are belong to us," though they are also responsible for founding and popularizing various internet memes, web sites, and trends.
There are many varieties of goon, depending on the particular forums they frequent at SA. GBS goons are often sarcastic and clever, while FYAD goons are elitist and abstract, BYOB goons are laid-back and random, CC goons are artistic and very critical, and ADTRW goons are anime-obsessed.
Goon2: OMG ur a goon 2?
Goon1: Wow yeah do you have stairs in your base belong to us?
Goons: Why do I have to pay 10bux to get into these forums? If it costs me an entire week's allowance, than I don't want to be a goon.
